D. D. PRICE MEASURING DEVICE Filed Aug. 29, 1927 Patented Apr. 7, 1931 ares n tes ter MEASURING nnvrcn 1 Application, filed August 29, i927. Serial No. 216,226.

This invention, relating to the art of sports, or gymnastics, has for an object the correct measurement and reading of heights from the ground of a cros'sor jumping bar for spring and pole jumping, and is especially directed to the securance of the proper meas urement of the distance between the ground and that bar, even to the specific consideration of the flex in the bar particularly intermediate of the pegs on the standards by which the-bar is sustained.

It will be remembered that although the bar lying across the space between the stand.- ards, and on the upper side of the pegs thereof, while ordinarily supposed to be substantially horizontal, is in fact bowed to a sufticient extent to be important in calculations, as to minor parts of measurement, in closely contested cases, especially, and in fact, at any time, no readingwill be correct until and unless this fiexation is properly taken into consideration. It will thus appear that if a measurement is read at the standard for the height of the bar with relation to the ground,

that measurement will not be true as to the actual height at the center of the apparatus and between the standards.

To this end therefore it is an object of the invention to provide a measuring device adapted especially for use for measuring this height or distance substantially at the centre of the bar and intermediate the standards supporting it. I

An application of the invention is shown on the sheet of drawings, accompanying and forming apart of the specification, whereon Figure 1 is an elevation view partly broken showing an application of the invention,

Figure 2 is a similar view of the measuring device,

Figure 3 is a detail view of one of the measuring head, and

Figure 4 is a detail view of another measuring head. a

In these several views, similar characters of reference will indicate like views and parts.

The usual two standards, and 6, with their telescopic parts 7 and 8, and the cross bar 9, and the supporting pegs 10 and 11, and the e e I DAVID D. PRICE, OF GUTHRIR'OKLAI-IQMA' other appurtenances are of course not novel,

having naught to do with the invention.

These standards are supported on the usual bases 12 and 13, andmay be adjusted by the usual thumb-nuts 14 and'15.

For position centrally of or between these standards 5 and 6', is a measuring device, consisting of a tubular memberl6, provided with, an elongated slot 17 to receive and permit the movement of a measuring toe 18 carried by a rod 19 adapted to telescopically move in the tubular'member' 16 and'this rod 19 is also provided with a toe 20 for taking to the bar 2lthe pole jumping bar for the high or pole jumps. I

The tubular member 16 is marked off on both sides of slot 17the readings to the right being for'the flexing heights of the cross bar 9, while the ones to the left will give the reading for upper toe'20, when the bottom of the toe 18 reaches a given graduation. g It is to benoticed that each bar is accompanied vby a deflexing dotted line, showing, perhaps, exaggeratingly the fiexion in the bars 9 and 21, and it will alsobe noticed that the toes are dropped in the drawing to meet the flexed position so that, as stated in the object,'the flexed-height of the bars may be accurately measured as to distance from the ground. 7 j I Here is the operation: The measuring pole is set or positioned intermediate of the standards 5 and 6, the toe 18 being positionable to the top of the lower bar 9, when a reading can be taken from the lower side of the" toe from the graduations at the right of the measuring member. .This will give an accu-' rate reading for the bar plus the aforesaid flexion. That same toe, pushed on up the slot until the toe 20 is resting overthe upper flexed bar, will give 'a' reading by being placed at .the

raduations at the left of the measurin rod. 5% a Of course, it is understood, that" by the w usual devices each of the telescopic rods either in the standards or the measuring devicemay be fixed in place temporarily.

Having thus described, this invention, I claim:

1. A measuring device, consistingof an elongated longitudinally slotted shell, a rod telescopically movable in said shell, 21 measuring toe carried at the outer extending end oi the telescopically movable rod, a second measuring toe carried by the 'rod and protruding through the slot, there being graduations on each side of the slot one for determining the distance from the first mentioned toe to the remote end of the shell, the other for determining the distance from the second toe to the remote end of theshe'l-lz 2. A measuring device, consisting of an elongated longitudinally partially slotted shell, a solid rod slidable Within the shell, a toe secured to the inner encased end of said solid slidable rod, and protruding through the slot and beyond the Wall of the shell, an additional toe mounted upon theouter free end of the rod and laterally thereto, said I shell having multiple graduations adjacent to each side of said slot one for determining the distance f10111-,l1l16 first mentioned toe to the remote end of the shell, the other for determining the distance from, the second toe I to said remote end of the shell.
